Description of the invention (I) The present invention relates to a recording and playback device for a guide shaft fixing mechanism and a recording medium. The fixing member for fixing the guide shaft can be easily assembled. Taking a recording and playback device equipped with a disc-shaped recording medium as an example, it has a function of reading information recorded on the recording surface of a disc-shaped recording medium that is driven by a turn table (turn table), or An optical head written on a recording surface of a disc-shaped recording medium. The optical head uses a pair of guide shafts mounted on a base to guide the moving direction of the optical head so that it moves along the radial direction of the disc-shaped recording medium. The guide shaft fixing mechanism constituted by this fixed guide shaft method fixes the fixed ends embedded at both ends of the guide shaft on the base to determine the installation and fixing position of the guide shaft. If the mounting position of the guide shaft is shifted, the movement position of the optical head relative to the disc-shaped recording medium will be shifted, so the laser light emitted from the optical head cannot be traced correctly on the disc. A track on a flaky recording medium. Therefore, in the conventional guide shaft fixing mechanism, the two ends of a pair of guide shafts are embedded in the fixing member. In order to install each fixing member at a position determined on the base, four types required in the assembly process must be used. The fixing members are installed one by one at predetermined positions on the base. However, since the shapes of these four fixing members are roughly similar, they must be well distinguished. For this reason, if the assembler fails to notice the differences between the four fixing members, the order of their assembly operations will be lost. As mentioned above, in order to solve the above-mentioned problems, the present invention proposes that the guide shaft 4 paper sizes are applicable to the Chinese National Standard (CNS) Al specification (21 × 297 mmf) ------------ -------- Order--I--IIIIII L.

Description of the invention (flying) Recording and playback device for fixed mechanism and recording medium. The structure proposed by the present invention has the following features and effects. (Please read the precautions on the back before filling this page) According to the above purpose, the present invention provides a guide shaft fixing mechanism for fixing an end of a guide shaft that guides a moving direction of a moving body to a base. . The guide shaft fixing mechanism includes a first fixed end, a second fixed end, a bendable portion, and a fitting member. The first fixed end is used to fix one end of the guide shaft, and the second fixed end is used to fix the other end of the guide shaft. The bendable portion is connected to the first fixed end and the second fixed end, and the bendable portion is integrally formed with the first fixed end and the second fixed end, and has a part of a bendable characteristic. The fitting member is used for inserting the first fixed end and the second fixed end into a predetermined position on the base. According to this, because the bendable part is integrally formed with the first fixed end at one end of the fixed guide shaft and the second fixed end at the other end of the fixed guide shaft, and has a part of the bendability, the positions of the first fixed end and the second fixed end There will be no mess, and the installation positions of the first fixed end and the second fixed end will not change, so the assembly process can be easily performed. The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs is secondarily printed. Since the first fixed end and the second fixed end are fitted into a predetermined position on the base, the first fixed end and the first fixed end can be correctly connected. The two fixed ends are installed at predetermined positions on the base. The present invention further provides a recording medium recording and playback device including a reading head, a guide shaft, and a guide shaft fixing member. The read head is used to write and / or read data from the recording medium. The guide shaft guides the mobile read head in a freely movable manner. The base has first and second positioning reference members formed by fixing both ends of the guide shaft. The guide shaft fixing member is used to fix 5 paper sizes applicable to Chinese National Standard (CNS) A, 1 specifications (210 X 297 mm) 509918 7253pif.doc / 008 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Description of the invention ο) The first fixed end at one end of the guide shaft is used to fix the second fixed end at the other end of the guide shaft, and is fitted into the first fitting member of the first positioning reference member, and is fitted into the second positioning member. The second fitting piece of the reference piece. The first fixed end, the second fixed end, the first fitting piece and the second fitting piece are integrally formed, and at least a part of them is formed in a bendable form. Accordingly, because the guide shaft fixing member has a first fixing end for fixing one end of the guide shaft, and a second fixing end for fixing the other end of the guide shaft, the guide shaft fixing member is fitted into the first fitting member of the first positioning reference member. , And the second fitting piece fitted to the second positioning reference piece is integrally formed, and at least a part of it is formed in a bendable form, so the positions of the first fixed end and the second fixed end will not be disordered, The mounting positions of the first fixed end and the second fixed end will not change, so the assembly process can be easily performed. In addition, the guide shaft fixing member further has a mounting position restricting member for guiding the recording medium to a predetermined position. The mounting position limiting member is integrally formed with the guide shaft fixing member. Because the mounting position limiting member and the guide shaft fixing member are integrally formed, the number of parts can be reduced, and the efficiency of the assembly process can be improved.
